vibration, will produce the maximum. power from the fuel used, is extremely light in' construction and can be built with as many cylinders as desired.

With the foregoing and other objects in view,.which will appear as the description proceeds, the invention resides in the combinat on and arrangement of parts and in the.

details of construction hereinafter described and claimed, it being understood that changes in the precise embodimentof the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the pre ferred form of the invention has been shown. In said drawings v V Figure 1 is a view partly-in side elevation and partly. in section of a motor embodying the present improvements.

Figure 2 is a section on line 2-2 Figure 1, the valve gearing being shown in elevation. I

Referring to the figures by characters of reference 1 designates the cylinder having open ends and which is provided. with a central gas intake port 2 in constant communication with a valve chamber 3. Ports 4 and 5 are provided for establishing communication between the valve chamber 3 and a.

gas chamber 6 and an exhaust chamber 7,

respectively. A water jacket 8 may be extended around the cylinder and, where several cylinders arefemployed in one motor, this water jacket can be extended around all of the cylinders while a single gas chamber 6 can be provided for all of the cylinders and a single exhaustchamber 7 can likewise be provided for all of the cylinders. This will be apparent by referring to Figure 1.

The cylinderor cylinders are. arranged within a casing -9 having removable plates 10 in line with the open ends'of the cylinders' whereby access may be had readily to each cylinder at each end thereof. The cas- Specification of hetter's Patent.

ing 9 is of such size as to not only accommodate the various cylmders and their wa-' ter-jackets but also toaccommodate a crank shaft 11, opposed levers 12 and their pivots 13, and link connections 14 between'the levers and the cranks of shaft 11 The levers 12 are arranged in pairs, one pair bein provided for each cylinder, as shown in igure 2, the upper ends of these levers being connected to pitmen 15 which extend into and are pivotally connected to hollow pistons 16 which are oppositely disposed within the end portions of one cylinder and equi-dista-nt at all times from the port 2. The cranks on shaft 11 to=which power is transmitted from the pistons of eachpair are extended in opposite directions so that when pressure is simultaneously applied to both pistons, thus to produce corresponding movement of the pistons simultaneously, pressure will be simultaneously transmitted in opposite directions to two of the cranks on shaftll, thereby to impart a rotation to the shaft.

' The 'port 4 is normally closed by a valve 17' having a stem 18 contacting with and adapted to be actuated by a lever 19 fulcrumed on a post 20 or the like. An actuating pin 21 contacts with this lever and extends into the casing 9 where it contacts with an actuating. lever 22 fulcrumed inthe casing, as at 23 and provided with an antifriction roller-24 which contacts with and is adapted to be operated by a rotating cam 25 on a shaft 26. vided and has a cam 28 designed toengage a roller 29 carried by an actuating lever 30. This lever is adapted to transmit motion through a pin 31 to alever 32 which in turn is adapted to-press on'the stem 33 of a valve 34 which" normally closes the port 5. The valve chamber 3 constitutes an explosion chamber and a suitable spark plugor other ignition device indicated generally at 36 may be arranged'therein.

the valve 34 will open automatically per: mitting' the burned gases to exhaust into the 'chamber 7. On the completion of this ex-;'

- haus t stroke of the pistons, the valve 34 will close automatically and" the valve" 17 will open; automatically and permit the refilling o the explosion chamber and that portion-- if of the cylinder between the pistons 16.

Obviously by having the mechanism arranged so that the explosions will occur in the several cylinders v successively, a high powered motor can be obtained and there is practically no limit to the number of cylinarranged as described. i l

By utilizing oppositely working pistons arranged'inpairs, all vibration is removed ders that could be used by having the parts and by utilizing the peculia-rcon'struction set vfo'rth,a'great'saving-of fuel can be effected iev and it becomes poss1ble tou s'e a lowergracle' When the pistons us causing the is- "oil. than would otherwise be advisable, be.- cause of the high compressionobtained.
